To all whom it may concern.-

Be it known that I, MELCHI SCOTT, of the city of Fairfield, in the county of J efi'erson and State of Iowa, have invented a new and useful Improvement in Tire or Hoop Benders; and I do hereby declare that the following isa full, clear, and exact description of the construction and operation of the same,reference being had to the annexed drawing, making a part of this specification, which is a view in perspective.

k k represent the bench; at u, the legs; 1 l, the lever; andpis the pulley on the end of the lever, fastened by side irons, 2, by means of screw-bolts or rivets, a bolt or pin passing through the ends of the side irons and through the pulley, which revolves when it is operated upon.

a a is the graduating-staff, passing through I the hind end of the lever, which is fastened by a thumb-screw, I, by which it may be graduated up or down to any point or number required.

Number arepresonts the braces on the front end of the lever, fastened at the upper end by rivets or screws, and at the lower end of the same a bolt passes through, by which the adjustable rack under the bench is made to move by the operation of the lever.

' 9 is the adjustable rack, which is attached to the lower end of the curved side levers by means of a bolt. I

1' represents an iron cross-bar at the hind end of the sliding apparatus, bent on the ends through which the sliding apparatus passes.

Number 1 is'a cross-bar fastened to the front legs, and which supports the adjustable rack.

which the boxes are fastened to the sliding apparatus, and graduated by means of slits m m to any width tire.

The sliding apparatus and the pinchers, combined with the side levers, and the ad justable rack, which, being operated by the lever l l, brings the bar forward until it begins to bend, when the pinchers let go their hold until the next time the lever is raised.

2. The graduating-staff a in the lever ll, with numbers 1 2 3 4 5 6 corresponding to the numbers on the notched side plates, 123 4 5 6 by which the tire may be made larger or smaller by means of the corresponding numbers.
